This is a list of the settings needed to get Firefox to connect to the game successfully on both Armor Games & Facebook.
Firefox Menu/Add-ons/Plugins/Shockwave Flash "Always Activate"
Firefox Menu/Options/General, scroll down to: Performance... untick "Use recommended performance settings" & a new option will appear "Use hardware acceleration when available" tick this.
Firefox Menu/Options/Privacy & Security, History: Firefox will "Use custom settings for history"
tick "Clear history when Firefox closes"
click on adjacent "Settings"
Settings for Clearing History: Do Tick; Cache, Don't Tick; Cookies, (otherwise this would clear your in-game settings cookie from the flashplayer)
Browsing & Download History, Active Logins, Form & Search History, Offline Website Data are all optional, based on personal preference,
if you tick "Site Preferences" it will erase the filter lists for Adblockplus and prolly other types of adblockers. I leave this Un Ticked.
click "ok" to set & close the above settings window.
Cookies & Site Data: Select "Accept cookies and site data from websites (recommended)
Keep Until: "Firefox is closed"
Accept third-party cookies & site data: "Always" (unfortunately this is required to connect on Facebook)
ok, you should be good to go, the cache and the majority of superfluous cookies will be cleared each time the browser is closed but the cookie in the Flashplayer that retains your in-game settings will be retained, but you've allowed sufficient access for cookies to your browser to allow the game to connect successfully.
